SUCKER-ROD FOR PUMPS.

SPECIFICATION forming part of Letters Patent No. 372,804, dated November 8, 1887.

Application filed May 20,1887. Serial No. 238,868. (No model.)

To all whom t may concern:

Be it known that l, DANIEL JoNEs, a citizen of the United States, and a resident of granted to me February 27, 1883, No. 273, 234.

My present invention is carried out as follows, reference being had to the accompanying drawings, wherein Figure 1 represents a side elevation o f my improved sucker-rod joint, a part of which is shown in section. Fig. 2 represents a central longitudinal section of the same. Figs. 3, 4, 5, and 6 represent cross sections respectively on lines A B, O D, E F, and G H, shown in Fig. 1. Fig. 7 represents alongitudinal section of a modification of the invention.

Similar letters relate to similar parts Wherever they occur on the different parts of the drawings.

In myA previous patent above mentioned I provided the socket on its inside with prismatic projections, which were forced into the surface of the wooden rod when the latter was driven into the socket. and in so doing the prismatic projections on the interior of the socket caused longitudinal grooves to be cut on the wooden rod, by which the latter was correspondingly weakened and liable to become broken. To avoid this,andl`or the purpose of securing the socket to its wooden sucker-rod in a strong, simple, and substantial manner, I construct and arrange the parts as follows:

a is the wooden sucker-rod, provided with one or more annular grooves,a a,as shown.

b in Figs. l and 2 is the screw-threaded end or shank of the metallic rod-coupling, which is adapted to be screwed into a correspondingly screw-threaded female portion on the next rod-coupling, in the series. In one piece with the shank b, I prefer to make the longitudinally-slitted tube c, having the slits d d, as shown in Figs. 1, 2, 3, 4, and 5. The slitted metal tube c is provided with one or more annular depressions, e e, corresponding in shape with the annular' grooves aa on the rod a, as shown in Fig. 2.

The object of having the tube c slitted, as shown, is to enable its ends to be spread apart sufficiently to receive the rod a, after which the expanded portions of said tube c are closed around the grooved rod a, as shown in'Figs. l and '2, causing the annular depressions e e on the tube c to rest in the annular grooves a a on rod a. After the rod @has been introduced in tube c and the latter closed around the former, as shown in Figs. 1 and 2, I surround the tube c with the metal locking-tubef, havinga series of gluts, pawls, or projections, g g, f

which are detached on three sides from said tubef, as shown in Fig. l, and connected to the tubef in their upper ends only, as shown. Said gluts g are preferably made of increased thickness at their free ends, so that when they are pressed inward into the annular depressions e e on the split tube c the outside of said gluts shall be even, or nearly so,with the exterior of tubef, as shown in Fig. 4. By this arrangement it will be seen that the ends of the depressed gluts g are made to rest and bear against metallic shoulders on the tube c, and not pressed into the Wooden rod a, by which the wear and tear of the wooden rod a is prevented and a most strong and durable joint obtained.

When so desired, the annular depressionse e and the interior of tubef and its glutsg may be tinned, and after the parts are put together, as described, I may still further unite them by pouring molten solder or alloy through suitable perforations, lz h, (shown in Fig. 1,) madeinpipef,into annularrecesseseabywhich the tubes cfand glutsg are still further united together. Heretofore the socket end, where it joins the Wooden rod, hasvbeen made straight; but this is obj ectionable,as it is liable to cause breakage of the rod at or near the place where it abuts against the metal socket or tube, and to prevent such breakage I make on the end of tubef a pair of diametrically-opposed ears,i 13, byY which the union of the Wood and metal parts is materially strengthened both against lateral and torsional strains.

In the modification shown in Fig. 7 I em- IOO ploy independent slitted or divided metal angular rings c ef, adapted to rest in the annular recesses a/ a of the wooden rod a, thus dispens- 'ingwith the continuous 'inner tube, c, as shown in Fig. 2. In said modification I make shank Z1 in one piece with the metal tuhef, that is provided with glnts, paxvls, or projections g uf/,in the saine manner as heretofore described. After the shoulder-rings or parts c' e have been located in the annular grooves a a on rod ai, I insert the latter in tuhej and depress the gluts g g, as shown in the left-hand end of Fig. 7. Il" so desired, the parts that are to be united may be tnned and Still further secured together by means of molten solder or alloy poured between and around such parts, as above described.

If so desired, the outer metal sleeve,f7 in Figs. 1 and 2 may in some eases be dispensed with and the depressions e e on the slitted tube c he filled with molten metal or alloy, in the saine manner as a wipe-joint is made on lead pipes, or in a similar or equivalent manner, or Wound with wire or suitable material.

"What I wish to secure by Letters Patent, and claim. is

In a suekenrod jointdzhe Wooden rod ,having annular recesses a a', and the slitted metal tube c, having depressions e e, fitting into grooves af e", combined with the metal tuhef, surrounding the sleeve c, and having gluts or projections g g, constructed as described, and adapted to be driven or bentin their free ends against the recesses in tube c, as and for the purpose set forth.

In testimony whereof I have signed my naine to this speciiication,in the presence of two subscribing Witnesses, on this 16th day of May, A. D. 1887.
